Configuration for versioning, when rebinding the host from dev-server…

… to all interfaces

This is the discussion, for setting an absolute url as publicPath, when you're binding the dev server not to localhost but to any external interface (0.0.0.0) and disable host checking.

 You can now access the dev-server using the IP address to your virtual machine on
 port 8080 - e.g. http://192.168.1.1:8080.
+If you've activated the :ref:`manifest.json versioning <load-manifest-files>` you need additional configuration to alter the url used in your templates to the ``dev-server``:
+
+.. code-block:: javascript
+
+    if (!Encore.isProduction()) {
+        Encore
+            .setPublicPath('http://192.168.1.1:8080')
+            .setManifestKeyPrefix('build/')
+    }
+
+You'll receive a warning, when starting the ``dev-server``, that you used an absolute url for the publicPath.
+
+When you're using the ``dev-server`` in a docker container, configure accordingly and map the port from the ``dev-server`` (default 8080) onto a port on the host and provide this port on the host in the url used in the call to ``.setPublicPath`` above.
